In China, a “cuppa” usually means a cup of green tea. Green tea is a staple of traditional Chinese medicine and has been for centuries.

It is popular globally these days as people drink it to treat a wide variety of ailments. These range from mood disorders to digestive complaints, aches and pains and even cancer.

Canadian-Chinese nephrologist (kidney specialist) Dr Jason Fung is a big fan of tea – green and black. He is also a big fan of fasting.

Fung introduced fasting as a therapeutic option for patients about five years ago. That’s part of his Intensive Dietary Management program for weight loss and type 2 diabetes reversal.
